Re: [Rd] argument order for Math2 group functions in R 2.6.x (PR#10683)
Dear Brian, Are there many primitives that take more than one argument? I see, for example, that round() is another. Might it not be a good idea to provide a warning in the help file(s) that arguments must be supplied in the correct order?
